1)Alternatively,thevalue3x01canbepassedinaregister.
Battery status after execution:
low: the text/DB has been restored and the process is
complete, so further SYSWR K 3x0x instructions can be
executed immediately
high: thelastinstructionwasnotprocessedtocompletion;
before further SYSWR K 300x instructions, a SYSRD
K 3x00 must be executed to check the readiness of the
ashcard
When using the instruction SYSWR K 3x01, note the following:
● It is strongly recommended to execute a SYSRD K 3x00 before this instruction, to
testwhethertheashcardisavailableandready.
● Iferrorsoccurduringprocessing,e.g.becausenoashcardispluggedin,XOB
13 will be called where it is present, or the error LED will be set
